Ingestion: May cause irritation of the digestive tract. May be harmful if swallowed. Inhalation: May cause respiratory tract irritation. May be harmful if inhaled.
Is potassium hydrogen phthalate the same as potassium acid phthalate?
Why is potassium hydrogen phthalate good for making a standard solution?
Potassium hydrogen phthalate makes for a good primary standard because it is stable, high in purity, non-hydroscopic, highly soluble, non-toxic, high in molecular weight, cheap, and available.7 Feb 2018
What is potassium hydrogen phthalate and why is it used for standardization of an NaOH solution?
Potassium hydrogen phthalate (KHP) is used to standardize sodium hydroxide (NaOH) solution because of its slightly acidic nature. Since the mass of the given acid is high, the calculated molar concentration of NaOH will also be high during the titration process.
What is potassium hydrogen phthalate used for?
Potassium hydrogen phthalate is used as a primary standard for acid- base titrations as well as for calibrating pH meters. It acts as a buffer in pH determination. It finds application as a useful standard for total organic carbon testing.
How do you clean up a spill of potassium hydrogen phthalate?
First-aid measures after skin contact : Remove affected clothing and wash all exposed skin area with mild soap and water, followed by warm water rinse. First-aid measures after eye contact : IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.

Is KHP an organic acid?
KHP is a weak organic acid, Sodium Hydroxide is a strong base. When combined, an acid-base neutralization reaction takes place generating a conjugate salt and water as reaction products.
Is potassium hydrogen phthalate a primary standard?
Potassium Hydrogen Phthalate (KHP) is a classic primary standard substance in that it is readily available in high purity; is relatively inexpensive; is easy to dry; is neither hygroscopic, oxidized by air, nor affected by Carbon Dioxide (thus making it easy to weigh out); does not undergo decomposition during storage;
